Anilido ligands

Remarkably robust dialkylthorium complexes [Th(L)(CH2SiMe3)2] (L 13 or 14), supported by bulky bis(anilido) ligands based on a xanthene or 2,6-dimethylpyridine framework, were prepared by salt elimination from [ThCl2(L)(dme)] and 2LiCH2SiMe3 or by alkane elimination from [Th(CH2SiMe3)4] and H2(13) or H2(14). ...

Mono(cyclopentadienyl)lanthanide diiodides are readily accessible utilizing the very bulky l,2,4-tris(trimethyl-silyl)cyclopentadienyl ligand (= Cp ")- A typical example is depicted in Scheme 50.252 Cp" LaI2(THF)3 also served as a useful starting material for the preparation of a series of mono(cyclopentadienyl)lanthanum-anilido complexes.2...

Anilido-phosphinimines are another group of asymmetric monoanionic bidentate ligands, similar to anilido-imine ligands deriving from aniline-imines 1 (Scheme 19) [51]. Anilido-phosphinimines are obtained by deprotonation of the corresponding... 

Investigation of the catalytic activity of anilido-phosphinimine rare-earth metal complexes was exclusively reported by Cui and coworkers. Various anilido-phosphinimine rare-earth metal complexes were synthesized by deprotonation of aniline-phosphinimines II-A with [Ln(CH2SiMe3)3(THF)2] [53]. Interestingly, the deprotonation of II-A was followed by intramolecular C-H activation of the phenyl group on the phosphine moiety to generate dianionic ligands which coordinated to the metal center in a CA A -tridentate mode. The resulting complexes... 

To get a better insight into this reactivity trend and to eventually determine the real abilities of large Ae elements, our group has developed three families of heteroleptic complexes supported by various monoanionic ancillary ligands—anilido-imino, LN (30—32), phenolate-amino-alkoxy (LO (33—36), and 8-diketiminate BDI (37—39)—and used them for the intermolecular hydroamination of styrene derivatives and isoprene (Scheme 28.8, Table 28.5) [27]. 

Mononuclear nickel complexes containing hard hydroxo, alkoxo, or amido ligands can be prepared by methathe-tical exchange of halide. Boncella has reported several arylnickel compounds containing terminal anilido groups. The introduction of steric hindrance proves to be an efficient strategy to avoid the formation of... 

As already mentioned, reactive nickel amide, hydroxo, or alkoxo complexes can experience insertion reactions giving rise to new Ni-G bonds. The mononuclear anilido complex 114 reacts with dimethyl acetylenedicarboxylate, resulting in the formation of the alkenyl complex 151 (Equation (74)). The insertion of GO into the Ni-N bond of an unusual tricoordinated Ni(ii) amido complex yields a carbamoyl ligand that features an unprecedented rf -C,0...
